These packages run in their own environment and don't have access to a lua interpreter, therefore the scripts can't run. The packagers could enable the internal interpreter, or allow the package to link the interpreter from the operating system, or bundle a copy of lua with the package. If you use one of these packages and wish to use the lua scripts, please contact the package maintainer and suggest the above fixes.
### Linux and MacOS
Ensure git is installed on your system. If it isn't, use the package manager to install it. Then open a terminal and:
Ensure git is installed on your system. Git can be obtained from https://gitforwindows.org/, as well as other places. If you use the gitforwindows.org distribution, install the Git Bash Shell also as it will aid in debugging the scripts if necessary. Then open a command prompt and run:
If you don't have %LOCALAPPDATA%\darktable you have to start dartable at least once, because the directory is created at the first start of darktable.
## Enabling
When darktable starts it looks for a file name `~/.config/darktable/luarc` (`%LOCALAPPDATA%\darktable\luarc` for windows) and reads it to see which scripts to include. The file is a plain text file with entries of the form `require "<directory>/<name>"` where directory is the directory containing the scripts, from the above list, and name is the name from the above list. To include GIMP the line would be `require "contrib/gimp"`.
The recommended way to enable and disable specific scripts is using the script manager module. To use script manager do the following:
You can also create or add lines to the luarc file from the command line:
`echo 'require "contrib/gimp"' > ~/.config/darktable/luarc` to create the file with a gimp entry\
or `echo 'require "contrib/hugin"' >> ~/.config/darktable/luarc` to add an entry for hugin.
On windows from a command prompt:
`echo require "contrib/gimp" > %LOCALAPPDATA%\darktable\luarc` to create the file with a gimp entry\
or `echo require "contrib/hugin" >> %LOCALAPPDATA%\darktable\luarc` to add an entry for hugin.
## Disabling
To disable a script open the luarc file in your text editor and insert `--` at the start of the line containing the script you wish to disable, then save the file.
## Updating
To update the script repository, open a terminal or command prompt and do the following:
### Snap
cd ~/snap/darktable/current/lua
git pull
### Flatpak
cd ~/.var/app/org.darktable.Darktable/config/darktable/lua
